Bug#1062356: adios2: flaky autopkgtest (host dependent): times out on big host

[Paul Gevers]

Source: adios2
Version: 2.9.2+dfsg1-8
Severity: serious
User: debian-ci at lists.debian.org
Usertags: flaky

Dear maintainer(s),

I looked at the results of the autopkgtest of your package. I noticed 
that it regularly fails. The failures seem related to the host that runs 
the test. ci-worker13 is a beefy machine [1], while the other amd64 
workers are much more moderate [2]. The tests that time out after 2:50 
hours seem to all run on ci-worker13 (so, lots of CPU's and lots of 
RAM), while the other runs only take below 10 minutes (and seem to run 
on one of the other hosts.

Because the unstable-to-testing migration software now blocks on
regressions in testing, flaky tests, i.e. tests that flip between
passing and failing without changes to the list of installed packages,
are causing people unrelated to your package to spend time on these
tests.

Don't hesitate to reach out if you need help and some more information
from our infrastructure.

Paul
